PIGK-UP FOR SHOCK LOADERS.

Application filed March 2, 1925, Serial No. 12,726i Renewed May 12,1928.

This invention relates to improvements in shock loading machines particularly adapted for use in connection with harvesters or the like.

An important object of the invention is to provide a loading machine in which a retary or gathering mechanism engages shocks, hay or the like from the ground and deposits the same on suitable conveying means.

A further object of the invention is to provide a loading machine of the above character which is simple and compact in construction and which can be manufactured at a comparatively low cost.

A still further object of the invention is to provide a loading machine of this character which may be readily mounted upon the conventional type of harvesters or like machines. 7

Other objects and advantages of this invention will be apparent during the course of the following description.

In the accompanying drawings forming a part of this specification and in which like numerals are employed to designate like parts throughout the same:

Figure l is a side elevation showing my improved device mounted in connection with suitable conveying mechanism,

Figure 2 is a top plan view of the same,

Figure 3 is a vertical sectional view taken through the rotary mechanism,

Figure a is an enlarged front elevation of a portion of the same,

Figure 5 is a vertical sectional view through the same, and 4 Figure 6 is a transverse sectional View taken on the line 66 of Figure l.

In the drawings, wherein for the purpose of illustration is shown the preferred embodiment of my invention, the numeral 10 generally indicates an inclined frame adapted to permit elevation of the grain or other material for loading into a suitable conveyor. This frame includes suitable floor boards ll carrying side boards 12 adapted to prevent displacement of the material. The extreme edges of the lower portion of the floor boards are provided with projections 18, the purpose of which. will be hereinafter more fully described. A transverse shaft 14: is rotatably mounted beneath the inclined frame 10 near the lower extremity thereof, this shaft carrying a pair of,

sprockets 15 on each projecting extremity. A pair of main drive chains 16 are trained over these outermost sprockets and drive sprockets mounted upon carrier wheels or any suitable drive means. An inner pair of sprockets 17 are secured to the shaft 14: and are positioned within the side boards of the inclined frame. suitable chains 18 being trained about these inner sprockets and over suitable sprockets at the upper extremity of the frame, (not shown). The inner chains 18 carry a plurality of cross slots 19 thus providing a movable conveyor.

The structure thus described is common to most forms of grain gathering machines and therefore I do not wish to claim any part thereof. My invention relates more specifically to a rotary mechanism for engaging the shocks or other form of grain and depositing same upon the movable conveyor whereby it is elevated and deposited in a suitable wagon body.

Referring now to theelements comprising my invention, the numeral 20 designates a pair of angular reel supports bent to, suit ably engage the side boards of the inclined frame. and project slightly outward at the extremity. These brackets are adapted to support a pair of stubshafts 21 rotatably mounted upon the brackets 01 supports to provide means about which the reel mechanism revolves. The gathering reel generally denoted by the numeral 22comprises a pair of end discs 23 having formed at the central portion outwardly extending bearing sleeves 24. These sleeves fit snugly about the stub shafts 21 and permit convenient operation of the reel. The bearing sleeves 2d are enclosed by a pair of outer journal sleeves 25 which are retained in a stationary position by collars 26 positioned about the sleeves and secured-thereto by means of set screws 27. Formed on the lower poi-thins of the collars 26 are transversely positioned bracl-cet sleeves 28 adaptezjl to engage the angular supporting brackets 20. A pair of sprocket wheels 29 are mounted on. the outer extremities of the bearing sleeves 24: being secured thereon by means of set screws 30 or any suitable manner. These sprockets are drivenby continuous chains 31 trained over the sprockets 29 and the intermediate sprockets carried by the transverse shaft 14-, adapted to rotate the reel. The extreme ends ofthe stub shafts 21 carry a pair of.

upwardly directed bracket arms 32, the

lower extremities thereof being pro 'ided' with openines for engaging the extremities of the shaft and secured thereon by cotter pins or the like. The upper extremities of these arms are apertured and engage the angular extremities of a pair of braces 33 the opposite extremities of which are bolted to the side boards of the inclined frame 10. This construction is provided to render the stub shaft immovable permitting rotation of the bearing sleeves 24 thereon.

The framework of the reel between the discs is composed of a plurality of longitudinal rods threadedly mounted in or otherwise secured to the discs and positioned adjacent the peripheral edge thereof. A pair of cranks 35 are ecui'ed to the inner extremities of the stub shafts 21, crank pins 36 formed on the extremities thereof forming eccentric l iearings about which the grain engaging elements operate. It is desirable that the crank pins 36 be positioned forwardly of and in a horizontal plane with the lit .disc centers in order that the engaging mechanism may function with the greatest eiiiciency.

In the present embodiment illustrating one form of my improved loading reel T employ six cross rods Set which will permit tl e use of three prong carrying bars 37 adapted to operate through alternate cross rods. The iars 37 are preferably rectangular in cross section and are adapted to rotate eccentrieally in relation to the central axis of the discs 23. The mechanism adapted to operate the bars comprises three link arms 38 rotatably mounted upon the crank pins 36 and secured against displacement by suitable cotter pins mounted in the extremities of these pins. The opposite extremities of these arms are pivotclly connected with extension pins formed upon a series of V- shaped levers 39. Each of the V-shaped levers 39 provided with an opening adjacent the extremity of one of the pro jet-ting arms. in order to engage alternate cross rods, The levers are retained in position upon the cross rods by means of spacing sleeves 4. 0 positioned on the extremities of the rods between the lovers and the (llSL'S. The third projection arm of each of the shaped bell crank levers is secured to an extremity of the carrier bars 37, it being understood that the V-shaped levers are arranged in directly opposed relation upon the cross rods 3% and therefore actuate the carrier bars in parallel relation to the rods.

It is to be noted that my improved loading mechanism may be readily mounted upon the conventional type of harvesters without material alteration in the construction thereof or in any manner obstructing the eliicient operation of the machine. My improved loading device is designed to facilitate the gathering of grain in shocks or any other form without bruising or, in any manner subjecting the material handled, to undue abuse. The grain is engaged by a plurality of tines or rake teeth 41 arranged in alignment upon each carrier bar. These tines project from the bars and are preferably arranged in staggered relation upon the several bars. In the embodiment shown and described the tines comprise straight pointed members but it is contemplated that they may be arcuate in form for numerous uses of the mechanism.

In operation, the carrier bars and tines mounted thereon are so arranged that the rake teeth will extend in angular manner at the point of engagement with the shock enabling the teeth to firmly engage the shock due to their upwardly inclined position and carry it over the reel, the teeth being caused to move toward the center axis of the discs when approaching: the rear of the reel and disengage the shock. It is obvious from the arrangement of the link arms and bell crank levers that the carrier bars and tines or eeth secured thereto will project to the outermost position during the forward movement due to the eccentric position of the link arm crank pins. This will necessarily cause the teeth to positively grip the grain as it comes in contact with the reel causing -t to be thrown over on to the conveyor frame. As the grain is lifted by the teeth and deposited upon a traveling conveyor the teeth are withdrawn from the shock by movement of the carrier bars relative to the stationary cross rods. This operation will become apparent from the enlarged sectional view of the reel mechanism as clearly illustrated in Figure 3.

It is to be understood that the form of my invention herewith shown and described is to be taken as the preferred example of the same, and that various changes as to the shape, size and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claims.

By the term triangular as used in the claims, I mean to convey the idea that the three points, namely, the pivot of each rocker lever 39 on the drum head. the point of connection of the link 38, and the longitudinal axis of the fork bar, form a triangrle (see Figure It will be noted, however, that the fork bar is set back or inwardly on the lever so as to give sufiicient length to the teeth 41. The relation of these parts is such that the plane in which the teeth proiect outwardly crosses the imaginary line that connects the pivot of the lever 39 with the point of connection of the link 38 to the lever 39.

Having thus described my invention, I claim:
